Problems solved by technology

[0004] However, the above scheme has the following disadvantages: the degree of separation between oil and air is not enough, resulting in poor purification effect of subsequent oil and gas, and the condensing equipment used in the condensation process of oil and gas is not enough to completely condense oil and gas in a short time, resulting in low condensation efficiency

Abstract

The invention discloses an environment-friendly oil gas recycling method. The environment-friendly oil gas recycling method includes steps of S1, separating oil gas from air by the aid of the magnitude of adsorption force of adsorbents for oil gas/air mixed gas; S2, carrying out desorption treatment on the oil gas obtained at the step S1; S3, preferentially permeating oil gas molecules of the oilgas, which is treated at the step S2, through polymeric membranes under pushing effects of the pressures by the aid of the characteristic of preferential permeability of the special polymeric membranes for hydrocarbon, entrapping and exhausting air components and acquiring enriched oil gas; S4, sucking the enriched oil gas, which is obtained after treatment is carried out at the step S3, into pipelines by the aid of vacuum pumps, reducing the temperature of the oil gas by the aid of multilevel continuous cooling processes to condense the oil gas so as to obtain liquid and recycling the liquid.The environment-friendly oil gas recycling method has the advantages that the oil gas can be separated from the air, accordingly, the environment-friendly oil gas recycling method is high in oil gasand air separation degree, and good oil gas purification effects can be realized by the environment-friendly oil gas recycling method.

Description

technical field [0001] The invention belongs to the technical field of oil and gas recovery, and more specifically relates to an environment-friendly oil and gas recovery method. Background technique [0002] For example, the Chinese patent with application number CN201720338627.7 discloses an oil and gas recovery system, including an oil storage tank, and an oil and gas recovery and discharge unit connected to the oil storage tank, wherein the oil and gas recovery and discharge unit includes at least one adsorption tank, and the oil and gas The recovery and discharge unit is used to open after the pressure in the oil storage tank reaches the preset pressure and lasts for a period of time, so that the oil and gas in the oil storage tank pass through the adsorption tank, and the hydrocarbon components in it are adsorbed by the adsorption tank. The gas components of the adsorption tank are discharged into the atmosphere, and when the adsorption tank reaches the state of adsorp...
